' OPHTHALMIC MOUNTING.

Application filed m 10,

T 0 all whom it may concern type in which the frame of the mounting embodies two rings formed of non-metallic material and connected by a bridge of the same material all in an integral structure. An object of this invention is to provide a construction which will make it unnecessary for dealers to hold in stock, alarge I,

number of differently sized mountings in order 'to be able to meet-different facial characteristics. further object ofthe'invention is to provide forconnectingnosc rests to" a non-metallic mounting in such a manner that the adjustmentlof the rests will not disconnectthe latter from the mounting. A further object ofthe invention is to provide asimple' and inexpensive connection between the adjustable arm of I a nose rest and a non-metallic mounting.

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described; the novel features being pointed out in the appended claims.

In the drawings:

Fig. 1 is a rear view ofa mounting con structed in accordance with this invention,

the'temples being shown in section;

Fig. 2 is an enlarged fragmentary section on theline 2-2, Fig. 3 i

Fig. '3 is an enlarged fragmentary section showing the connection between the adjustable supporting arm and the non metallic frame;

Fig. 4 is a view similarto Fig. 3 of.a-n-. other embodiment of the invention; and

5 is a rear view of a mounting con structed in accordance with the embodiment illustrated in F lgu4. I

Referring more particularly to the draw} ings, 1 indicates the lens rings made of nonmetallic material such as Zylonite or. the like and connected by a bridging portion 2 also made of the same material and integral with the rings. The temples 3 pivotally 1922. Serial my 559,837.

connect-at 4 to extensions 5 provided on opposite sides of the frame;

A pair of padsor nose rests 6 arearranged to engage on opposite sides ofthe" nose of the wearer and with the temples 3 serve to support the mounting on the user. These pads or nose rests have sleeves 7 on their rear faces'mounted to turn on adjustable supporting arms connected with the frame. t 1

In the embodiment of the invention shown in Figs. 1 to 3, these supporting arms are formed of pliable or ductile metalwire bent to provide a portion 8 on which the sleeve? turns, a portion?) at one side of the sleeve to cooperate with the rear face of the. restb, in order to limit the swinging movement of the latter, and a bend 10con- -necting' withtheportion 8 and also 'with" a portion 11- extending forwardly above the sleeve. At the'forwardend of the portion;11 a laterally turned or U shaped portion 12 is provided. This laterally turned or U shaped portion is embedded'in" the 7 non-metallic material adjacent the junction between the bridging portion and one of the rings, thls result being secured by heating the anchoring or U shaped portion 153 and then forcing said portion into the non-, metallic material which flows about the U shaped portion, so that the latter finally assumes the position illustrated in Fig. 3.

After the non-metallic material is cooled, the connection is such thatthe pliable supporting arm may be adjusted to position the nose rest 6 so as to adapt it tothe nose of the wearer and this without destroying the connection between the supporting arm "and; the non-metallic material, the laterally turned "portion preventing the supporting arm from turning in the non-metallic -mater1al.

In the embodiment of the invention shown in Figs. 5 and 4 the parts of the frame are thesame The'pads 6 is formed in a known manner with a tubular portion.

7 between its ends. 'This pad connects with the non-metallic frame through the pliable, or adjusting arm which has a portion turning in the tubular, portion and" from. said turning. portion an arm 13 extends downwardly connected by a bend .14 with an upwardly extending portion 15 which by a bend 16 connects with a U shaped anchoring portion 12 which is embedded in the non-metallic material in the same manner as the anchoring portion illustrated in the embodiment of Figs. 1 to 3.

From the foregoing it will be seen that there has v been provided an ophthalmic mounting in which a non-metallic frame is formed from two continuous rings connected by a bridging portion and having nose rests provided with supporting arms anchored in the nonmetallic material adjacent the connection of the bridging portion With the rings. The connection between the supporting arms and the frame is such that the supporting arms may be bent to adjust the nose rests Without disconnecting the supporting arms from the non-metallic frame. This invention makes it possible for dealers in non-metallic mountings of this type to reduce the variety of sizes carried in stock, as one mounting may be adjusted to fit a large number of different types of faces.

What I claim as my invention and'desire to secure by Letters Patent is:

1; In an ophthalmic mounting, the com bination, \vitha frame formed of non-me tallie material and embodying a pair of rings, and a bridge connecting them, of nose rests each having an adjustable supporting arm provided With a rigidportion embedded in the non-metallic material a'djacent the connection of the bridgingpoi tion With one of the rings and formed to prevent the turning of said embedded portion in. the non-metallic material during the adjustment of the supporting arm.

2. In an ophthalmic mounting, the oon1- bination with a frame formed of non-metallic material and embodying a pair of -rlngs and a bridge portion connecting them,

rests each having an adjustable supporting arm provided with a U shaped end anchored in the non-metallic material adjacent the connection of the bridge portion With the rlng.

4. In an ophthalmic mounting, the combination with a frame, of nose rests, each having a bearing sleeve on the rear face thereof, and pliable supporting arms for said rests, eachhaving a portion turning in a bearing sleeve a portionextending from the forward portion offsaid bearing portion to co-operate with the rear face of the nose reststo limit the movement of the latter, a portion extending upwardly from the rear portion of the bearing portion, and a portion extendin forwardly from said up- Wardly extending portion and connected with the. frame.
